[MPlayer-users] Why 720x540 as opposed to 640x480?

Hello everyone,

I'm still learning about DAR's and PAR's...I'm now wondering why does mplayer 
upscales (vertically) my NTSC DVD to 720x540 as opposed to horizontal 
squeezing as in 640x480?  I know the goal is to obtain a 4:3 AR but isn't the 
latter best for interlaced material (still keeping the 480 lines)?

I'm just trying to understand this :)

Thanks,
Jorge
